Jerry, Removing unused inner layer pads is a standard CAM function. Most CAM software tools identify these as pads with no trace termination or connection and/or no drill assignment. I've seen some customers specify in the notes on the fab drawing that it's ok to remove them. If there were any question about usage, the fab shop should leave them as is or preferably contact the customer.
