No theoretical reason why you can't, but there must be a good reason to do it, as the critical path is what you need to concentrate on to get the project completed, as extending the duration of a project is not normally a good thing to do. Adding dummy tasks into a schedule is a dangerous thing to do, especially on the critical path and if they are not clearly marked, not resourced or not costs. The only reasons I can think of putting a dummy task in, is to:
1. Show when resources assigned to your project are available when you are not using them (waiting time) so they can be used on other projects;
2. Showing when you could undertake other tasks not related to the project (e.g. take project related additional 'nice to have' training, take holidays etc);
3. Making some kind of contingency visible on the schedule.
You need to have a good justification on why you are doing it.

What is dummy task for a project?
A dummy task is a task representing nothing (no actual work done), but is there only to clarify the activity network diagram. Source: http://www.pmhut.com/critical-path-mapping-with-activity-network-diagrams
How does total slack impact a project network's critical path?
Total slack refers to the amount of time a task can be delayed without affecting the project's overall timeline. If a task on the critical path has total slack, it means that the project's completion date can be extended without impacting the critical path. This can provide flexibility in managing the project's schedule and resources.
What a critical path in a project is and how it is determined?
The longest route through a series of interrelated tasks. Should a task on the critical path slip then the end date of the project would be jeopardized. Critical Path Most projects contain a large number of tasks. The critical path is the order of tasks that must be finished for the project to be considered complete. This path dictates the final finish date of your project plan. The critical path is not primarily a list of vital tasks. It is a specific sequence of tasks, each task depending on the last. As the project progresses, different sequences might be named as critical. Consider a project with two vital task sequences which we'll call selecting the new office site and Moving in to new offices. At the onset, the first task is projected to take 9 months and the second is projected to take 6 months. Since the first task will take longer and is deemed as being on the critical path. After three months work, should the first task perform ahead of schedule with a new estimate of 5 additional months more while the second has been delayed by three moths the latter task would now be on the critical path? What is a Critical Task The definition of a critical task is any task that with a change of duration may positively or negatively affect the end date of the project if delayed Tracking the Critical Path The Gantt chart and network diagram two classic views in MS Project will display critical tasks and links in red automatically to make these tasks easier to observe and report. Slack Time Total slack is the amount of time that lies off the critical path. In other words changes to the duration of these tasks may or may not affect the critical path. Slack is the amount of time a task can be delayed and still be on schedule. A 5 day task with a 10 day deadline has 5 days of slack. A task with no slack is automatically critical. Imagine two tasks due to finish at the same time. Packing computer equipment with one day of duration and packing files with four days duration. If they both started at the same time the pack equipment tasks would have three days of slack. http://www.mousetraining.co.uk/training-manuals/Project2007.pdf for a training manual and quick key card

How can one determine the critical path in a network diagram?
To determine the critical path in a network diagram, you need to identify the longest path of connected tasks that must be completed in order to finish the project on time. This path has zero slack or float, meaning any delay in these tasks will cause a delay in the overall project completion. By calculating the duration of each task and their dependencies, you can identify the critical path.

What is critical path?
In Project Management the Critical Path is the series of tasks that must finish on time for the entire project to finish on schedule. Each task on the critical path is a time critical task. You can also think of it as:the longest path from start to finishor the path without any slack,the path corresponding to the shortest time in which the project can be completed.
What is the net result of reducing the duration of a task crashing not on the critical path?
By reducing the time to completion for a task not on the critical path you can still reduce the duration of the project. Crashing a non critical task will also free up resources.
What is the importance of critical path and critical task estimation?
The importance of the Critical path is that helps you in reducing risk, contingency planning, and project planning.
What is the net result of reducing the duration of a task not on the critical path?
reduction in the project duration

What is the differences between critical path and slack time?
The critical path is the longest path through a project, indicating the shortest possible time needed to complete the project. Slack time is the amount of time a task can be delayed without delaying the project completion. Tasks on the critical path have zero slack time, while non-critical tasks have slack time.

Difference between critical and non critical task in real time system?
the difference in critical and non critical task in a system is critical task are processes that the computer needs to operate correctly they are must have programs. Non critical talk are task that are running or can run but is not a crusial part if the task is deleted or ended then the OS should still fuction properly
