Maybe, maybe not. We have runways 1000' centreline to centreline. SFO's are 750'. Our tower radar displays the extended centrelines out to about 8 miles and because of the range of the display, we could (not saying we would) see if an aircraft is on the wrong centreline at 8 miles.
If SFO tower has a piece of radar equipment that we call Airspace Warning Feature, they would receive a visual and audible alert that he was incorrectly positioned at about 2 miles out. That would coincide with the issuance of missed approach instructions.
