The issue is that the actual WiFi/Bluetooth antenna bar doesn't contain any of the actual driving components for Bluetooth or Wifi. The driving components are integrated into the board, and can only be removed if you have micro-soldering skills.
However, @danj did have a good alternative solution to this in [post|163760|a similar question|new_window=true]. To sum it up, all you should have to do is turn off the WiFi and Bluetooth services through the OS and set up a second user account with the services disabled by admin.
