Windows 7 pro product key for windows 10 pro for workstations?

[windows user]

I have Created a windows 10 pro for workstations to go thumb drive and have a windows 7 product key. Can I use that product key and still keep it as workstation? It has already been entered into the system and is activated but, it says windows 10 pro I would like pro for workstations. This may sound dum, but do I still have all the features of windows 10 pro for workstations.
