Does a turbojet aircraft restriction on a SID or STAR also apply to turbofan aircraft?
The term "turbojet" in this context is used a bit more loosely. The pilot-controller glossary document from the FAA defines it as follows:


  TURBOJET AIRCRAFT− An aircraft having a jet engine in which the energy
  of the jet operates a turbine which in turn operates the air
  compressor.


You can see this is general enough to include turbofan aircraft as well. The main distinction is vs. a turboprop, where the turbine drives the propeller.
