There are many cheaper CAN USB interfaces.
And of course you can use the integrated CAN in the BeagleBone.
You have to add a transceiver and for system security galvanic isolation.

Because canboat is open source, it should be easy to adopt the SocketCAN or 
can4linux CAN message format. In any case you don't need the J1939 software.
Only receiving NMEA frames is easy, decoding the PGNs requires knowledge of 
it.
