I think you missed the point that is relevant. If the OP doesnt get permission and his company dont allow it if by some bad luck the licensing authority come knocking they will visit his company and not the OP and then even though he has a TV licence (so thats a tick for your reasoning) his company know he's broken IT policy rules and this could lead to who knows what. Also they might question why the VPN traffic suddenly shot up alarmingly from someone in another country. ie dont get yourself into trouble. Same principle if you take a pool car out and break the speed limit. Your company as the registered keeper gets the notice first, not the driver.
So the moral is check with your company if they allow it. If you don't want to do this then accept the potential risk also.
