Should be able to get 500mA at 5V off of any standard USB port on the Kangaroo, no need to use the microUSB charge port.
More than enough for a small (30mm square) fan.

ON A SEPARATE NOTE:

So I am wondering if the addition of the fan motor powered by the USB port on the Kangaroo is legal in FRC.

The fan is a motor, you fabricated the mount it wasn't part of the Kangaroo. An internal laptop fan in a COTS device wouldn't be an issue and we've taken that through quite a few inspections.

I wonder if you might be forced to power the fan from the RoboRio control side to cool the Kangaroo. Such that it only runs when the robot is enabled or only when the robot is powered on. Cause you could leave the co-processor on between matches. I haven't seen anyone been asked to turn a co-processor off as long as it was legal to start with (IE it could not control a motor like this case - in this case powering the fan from the Kangaroo might be a FRC illegal thing to do).

ANSWERING MY OWN QUESTION:

So I think the master breaker requirement and R52 in 2016 put you in a situation where the master breaker must be able to turn off the Kangaroo cooling fan. In that situation that's not too bad. You really care the Kangaroo doesn't CPU throttle when you are depending on it.
