Yes you can cut there.


Those are the wrong couplings to use. You need to use a no hub fitting. Also the no hub fitting needs to be cast iron to pvc. Both pipes are different sizes. Those fittings you have will promote cloggs because the two different pipe materials will not be butt together. They will be at un even elevations. Its also code to use a no hub/mission coupling.

The next thing is your vent. What are you going to do? You need to add a 3x3x2 y to that toilet arm, dump the sink into the 2" and vent the sink up through the roof, or tie into the exsisting bath vent above the flood plane. This is code.
