Don't get too hung up on 'what you burn' during an exercise bout of any type. It is far greater to worry about what you do between your exercise bouts that make the difference.
The main real time the empty stomach thing comes into play is if you are pretty lean already. You really have very little 'say' no matter what as to what substrate your body uses for fuel.
Now, that being said, if you do just steady state type cardio at a low level, then probably no matter. However, if you do for instance a HIIT session, an intense HIIT session can rival a weight workout. Your body has to 'recruit' fuels at a very quick rate for this or any explosive type work. Fat generally cannot be mobilzed that quickly.
Work for your needs. Again, using a 'virtual hammer', I wish I could pound this into folk's heads. What you do between a workout of any type determines what you get out of it. Just as you don't gain muscle during a weight workout, so it is you burn very little fat during a cardio workout.
