There are hundreds of BT devices everywhere that people waiting for a flight hang out. Without automatic scanning for the specific purpose of catching weird names, it'd be near impossible for the weird name to ever show up for anyone except the owner. And most devices don't advertise their BT name unless in pairing mode, so no, it wouldn't show up in the security screening either.
