It is possible but not easy – you would have to set up a Virtual Machine and run V10 on this Virtual Machine (in effect having V10 on a simulated computer that runs on your main computer). The software is free but unless you are reasonably IT literate, you would be better paying someone to set it up for you.
Another way would be to pick up a really cheap PC from somewhere and use that (maybe network the 2 together). You would have to be careful not to lock your USB key out and in both this and the above scenario, you could only run 1 version at a time with a single key.
