You will have to do a Custom install of Word97 so that it goes into a
different folder. You will not be able to run both versions simultaneously
and switching from one to the other will probably involve an installation
dialog appearing on the screen while the registry settings are updated for
the version that you are starting.
I can't really believe however that you should need to do this for the
purpose that you mention. Any practice that you do on XP should be of
benefit when you do a test on 97.
