That said, I expect you can fool Facebook for a while with high probability. You might need to commit fraud and/or tax evasion to do so, so that raises the bar.

The biggest risk of leak would be during usage of their services like their app and/or website on personal devices. If you can work there while only using their issued work laptop it would be pretty easy to contain by sticking it behind a VPN router.
