Could tranfering a computer with a dormant virus to another room activate the virus?

The answer is 99% no. Viruses normally act either on opening or running of a file or program. Some however are triggered by the caching or counting of keystrokes or dates etc. Just by moving from one room to another should not trigger a virus unless you have some sort of special hardware with the machine that detects changes in positioning like a GPS or a change in magnetic fields. So the answer as stated is fairly certain to be no.
