In a desktop situation, you have a card with an detachable antenna, and the card / antenna unit can be confirmed to comply with whatever regulations are in effect. In a laptop, the antennae are usually part of the laptop body, and only the card itself is replaceable, so the manufacturer is locking out cards that it has not tested with the built-in antennae.
