Yes.  APCircuits actually tells you to do this to simulate a Score Line.
35mil holes on a 50mil grid for their Proto Service.

Also a line of very small holes, ~10mil to ~42mil depending on various board
factors like board thickness etc. can be used along Tab Breakaways
so that you don't have to have a secondary sanding operation.
See IPC-7351A 3.4.8.3.
