Im still not sure if I can remove this safely or without introducing 'problems'. Maybe i should just try it.

The first cap is probably to remove the DC offset from getting to the output stage. The second one is probably to keep DC from the output of the unit. I assume the op-amp on the output is running with Plus and Minus rails, so as long as this stage is referenced to ground, you probably don't need the last cap. However, It also keeps the output from going to the rail when problems occur. As long as the op-amp never fries, you may be alright.
