In theory I can't see why not (it is unlikely that tar would have a
place in this process...).

NetWorker writes multiple files (hundreds) to the tape so you would
need to run your dd multiple times.

You would also need to ensure that your destination tape was able to
hold all the data that was on the source tape.  Usually NetWorker fills
a tape as full as it can (it writes until EOT), and different tapes
could have slightly different capacities (they are probably
manufactured with slightly different lengths, and then media faults
will chew up different amounts of tape, and some drive types are
reputed to change compression algorithms etc to match the incoming data
rates).
