I would, even if it's dual booting with current OS and use 3 different Microsoft accounts. Worst case is you wasted a few hours and back to how you are now.
It's lookin more likely it is indeed free and no license required. If it is the case, remember you need to be signed up to the insider program, go to the Microsoft site and enrol. and your Microsoft account needs to be activated in windows 10.
Even more news sites talking about it now.

Edit - how come you need more licenses anyway? Or are you still running lots n XP.
