I reused a Win10 Pro key from a mini PC from 2015 onto a brand new build and it worked right away. Not sure what the difference is with your situation. Maybe it was your license type?
Laptop licences are linked to the hardware. You technically do not have a key to begin with.
It was the license that came on an Acer laptop. Completely non transferable per Microsoft.
