Dell Optiplex 990 - Swap System Drives - Roll Back OS

Hi Gang

Happy Holidays!

Is there anything about the Logic Board (or in the Bios) that would prevent someone from taking out a system drive (formatted with W10) and putting in (swapping) a different hard drive and formatting it with W7 Pro? And then returning the other drive (formatted with W10), or reformatting that drive again with a fresh install of W10?  

Is that possible? 

Thank You
