Yes but….if there’s any ICs on such boards and they go wrong you have a repair issues (esp as they’ll be surface mounted) any repairer would have to have that specific game to be able to test the board, or make a call out.
Even a dud LED is going to be a problem to repair, I cant solder on a new surface mounted LED but I can change a 555 bulb in a socket
I’ve recently had an issue with bespoke boards in my Stern Star Wars, I was lucky that replacement boards were still available (though 1 had to be bought from Germany and the other from America) and the boards (the size of a couple of credit cards) were expensive so imagine what a board the size of half a playfield would cost
