I would call that a software emulator; the fact that it runs on some microprocessor eval board doesn't make a difference.  Running SIMH on a Beaglebone would be analogous (though easier).

When you said "hardware emulator" I figured you meant an FPGA implementation of a VHDL or Verilog model of the machine.  There are a bunch of those for a variety of DEC computers.  One I have looked at is this one: http://pdp2011.sytse.net/wordpress/ which incidentally is also configurable to implement a choice of PDP11 model.
