I don't think so. I believe it is a filter for the lymphatic system.
In anatomy and physiology the two terms are used to define a structure, or its anatomy or describe its function, or physiology. As for lymph nodes, they are specialized tissues whose main purpose is to filter and cleanse lymphatic fluid. So, the structure is lymphatic tissue and the function is to purify lymph. The two terms are always associated with each other, though for convenience and clarity can be discussed together. So, whatever you were researching that brought up that question for you the way you asked it makes me think that there is some more information for you to uncover that will help you understand those concepts better.
A lymph node.
A reactive lymph node is the same as an enlarged lymph node. Lymph nodes can become enlarged for a variety of reasons, most of which aren't serious. The ICD code for a reactive lymph node is 785.6.
A paraaortic prominent lymph node is a lymph node more noticable than the others and found near the aorta.
The difference between incision and excision of lymph nodes is very simple. The incision of a lymph node is when the biopsy only takes part of the lymph node during surgery. The excision of the lymph node is when the whole lymph node is removed.
A sentinel lymph node is the first lymph node that drains a cancer. If a cancer has not spread to the first draining lymph node near a cancer, there is a high likelihood it has not spread elsewhere.

The submandibular lymph nodes are located between the salivary gland and the mandible. Their function is to drain debris and waste substances from all regions of the oral cavity.
It's a lymph node that drains an inflamed area. The source of the inflammation can be bacterial-viral infection, immunological disease, or malignancy.
A sentinel lymph node is the first lymph node that drains a cancer. If a cancer has not spread to the first draining lymph node near a cancer, there is a high likelihood it has not spread elsewhere.
Of primary importance to stage determination and regional lymph node involvement is identification and analysis of the sentinel lymph node.

A lymph node is a small ball or an oval-shaped organ of the immune system.
