I own a bluetooth speaker from the Boom brand and it has obviously the model name as bluetooth ID.

Changing it would require installing an app that I don't really want to for obvious reasons. Additionally some bluetooth device never really turn down completely and still advertize their bluetooth ID via BLE so the teenager in question may not even have realized he could change anything and the commands given (turn off bluetooth) were completely stupid as it wouldn't change anything if people turned down their smartphone bluetooth.
