"Get another laptop, same model and specs as one of the ones you're about to hand back, then image that disk onto the new one. Hand back both company lappies."
Depends. If the HDD is running fully encrypted (which it should be) then imaging or swapping HDDs might just end up with a disk that won't boot without the keys. Back when BitLocker was still a thing, swapping an encrypted HDD into an identical box didn't work so I assume the current equivalents will do the same.
