I read an article testing the same disc drive in multiple PlayStations and they continued to work. My guess is that Sony pays for console X to be able to use a disc drive when one is inserted, and then pays for console Y when one is inserted. They probably can check the ID of the disc drive, but they also probably don’t care that much.
I wouldn’t be surprised if it uses an internet connection to verify the disk to try and prevent used sales or pirating
