Hi there
If it's a RETAIL key (W7) it should work WITHOUT having been previously installed on the old computer -- however if you are in any doubt simply install W7 on it --forget about any drivers / apps so it should only take around 10 - 15 mins at most - activate, wipe HDD and now install W10.
Can't really understand why people are making a fuss about this -- you don't need to install W7 with all your apps , updates etc etc -- just a bog standard install with all defaults straight from the install disk --you aren't going to RUN W7 as your normal OS - and the OP wants a CLEAN install of W10.
You probably won't even need to install W7 --just try W10 with the key -- but if you are paranoid do the quick install (minimal) then activate, wipe HDD and clean install W10.
Cheers

That's not true. It is totally possible to in-place upgrade Windows XP or Windows Vista to Windows 10 keeping all compatible apps, personal files and settings, you just need to be a bit creative

Anyway, as the OP has Windows 7 product keys, he has already got the best advice: Clean install Windows 10, activate it with Windows 7 product key.
