If you are looking for speeds on the order of 0.0024 Mbps (2400 baud) then maybe. You could use amateur radio packet radio gateways and radio modems and set something up.

You could do it legally (in the US) by paying a token amount and getting a part 90 business license or possibly by using MURS frequencies instead of FRS/GMRS.

The spectrum is reserved for actual business use; "amateur radio, but with encryption" is not on the list of eligible use cases for a business band license [0]. If you're willing to break the law, wouldn't it be simpler to go ahead and transmit encrypted on the amateur spectrum than to submit a fraudulent application for a business band license?

I don't think there is enough channel bandwidth on those bands to support wifi.
