Yes, this means your license is linked to your email address instead of the PC.
this shows you what to do to transfer it onto another PC -
Reactivating win 10 on new hardware
You can only have it on 1 PC at a time.
Most laptops come with windows pre installed and until a new version of windows is released (if ever) then you likely get Win 10 on laptop anyway. Many big OEM have special win 10 licences that are tied to the hardware and can't be moved
I have to guess your install was an upgrade from win 7 or 8 to allow you to move it.
