One of my clients wishes to install a garage door to his two car garage.
The header beam is too low and needs to be reduced in depth by about 4.5
inches. One of the solutions proposed by the client's contractor is to
remove the bottom three laminations and add a new post + pad  about
mid-span. The current Glulam beam is 21 inches deep. It works as a 16.5
inch beam for the reduced span.

Question: Is there a problem if he cuts 4.5 inches from the bottom of the
Glulam?

Yes.
 

The tension lamination splices are specifically located in this zone and as you creep up into it's depth you may be getting into less desirable laps and wood.
