The simple rule for Windows 10 is that a digital licence is linked to the unique hardware ID of the PC and stored on the Microsoft activation servers. A digital licence does not contain the product key that was used to activate Windows. In fact, most Windows 10 installs will only have a generic key recorded in the registry.
Provided the hardware you move Windows 10 to already has a digital licence for the edition of W10 you put on it (Home or Pro) then Windows will activate. The hard drive is not part of the hardware ID, so can be swapped out for another one without loosing the digital licence. The motherboard is the main contributor to the hardware ID.
