The AS5306 magnetic encoder module A and B outputs will certainly connect to the the parallel port fine. You can configure Hal to do quadrature decoding from the parallel port, but your linear stage can't go very fast. The AS5306 has 40 pulses / 2.4mm = 16.7 pulses/mm. If I recall correctly, LinuxCNC can typically read maybe a couple thousand pulses per second from a quadrature encoder via the parallel port, so you would be limited to ~100-200mm/sec in speed.
