If your TestComplete license is node locked, then you can only develop and run on that one computer, but you may be able to use Remote Desktop from that machine to access other computers for testing.

If you are going to have a team where more than one person is going to be using TestComplete, then you may want to look into floating licenses. They can be shared, and if everyone is not going to be working on TC at the same time, that is a good way to go because you don't need one license for each person. Projects created on any of those computers can be shared with any other instance of TC.
