Yes, it can, but only if you are testing continuous current ratings.
When you start testing bursts, it gets a little tricky. You know that the PWM signal for an ESC is 1ms (rev/brake) - 1.5ms (neutral) - 2ms (wot). So, you already only have 0.5ms to play with when going from neutral to wot (rev/brake is not used). If you "cap" the ESC throttle at say 50%, you then only have 0.25ms to play with. Now, you are really reducing the resolution of the signal so when trying to make tweaking adjustments, you may not have enough resolution to adjust the output exactly where you want. The use of an aircraft ESC may help with this since it doesn't have reverse and so it has the full 1ms of throttle range to work with. Personally, it would be easier to make load modules so that each one is X ohms, and you just parallel what you need to get into the ballpark.
I hope that made sense.
