Aren't there legal exceptions when you give out something? Otherwise it could cause a lot of trouble to charities that work with donations. It would be a big problem for the recycling industry too.
Even if there's a legal loophole (I doubt it), why would Apple want to become known as a reseller of stolen laptops? I don't know the legal technicalities, but if you have a reasonable suspicion that an item might be stolen, then reselling it is at least unethical and probably legally dubious too.
