Can I use Windows 7 Pro Key to upgrade my Windows 10 Home to Pro?

I just bought a new laptop with Windows 10 Home Edition. However, I have an unused Windows 7 Professional Key that I haven't used yet, and I was wondering if I could use that to upgrade my Windows 10 to Pro. Just to clarify, this is not talking about a clean installation of Windows 10 and using the key to activate it, this is asking if you can use the Windows 7 Pro key to change my existing Windows 10 Home product key and upgrade.
