On a LHD car, it _is_ that simple.
On a RHD car, it's a ten-hour job involving removing the entire steering column 
and pedal assembly.  So give thanks.
You can leave the actuating rod from the old cylinder in place.  The only thing 
to be careful of is to check that, once installed, a full pedal depression 
caused the piston to sweep the _entire_ length of the master cylinder.
Otherwise you'll never get it to bleed properly.
