There is nothing which can prevent someone from configuring a machine to use any IP address they want to set, assuming they have admin access to that machine. Normally, you don't grant physical access to your network for people you don't trust, but if you need to provide network access to untrustworthy systems, then you need to look into setting up access control via VLANs, or maybe PPPoE, or something similar where you can isolate their network and only let their traffic talk to other things if they connect "properly"...
