Yes, someone can go to the trouble of obtaining a known corporate MAC
address and MAC-spoofing their personal device so they can PXE-boot a
corporate build on a VLAN that is otherwise useless.  If your
corporate build on it's own is precious enough in itself that you
worry about this eventuality, then make the build server insist on
authentication before the build initiates.
