Yes, I have removed mine.
Do you have the key? If not, you will need to "pick the lock".
The point is this, you need to put the lock into the "LOCKED" position. This is where the handle will rotate on the shaft.
Once that is done, the entire lock assembly and square shaft will be able to be pushed out from the chrome handle.
I did not have a key, but I was able to get the 4 pins to align so that I could rotate the lock and then it easily pushed out.
