Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter
No reason not to push the wheel back, but you may not get the desired result. Bikes with horizontal dropouts were built with the understanding that the end of the slot wasn't critical, since the owner would not using it as a deadstop. So you have no assurance that the wheel will be square in the chainstays when pushed all the way back on both sides. Of course, if the wheel does line up well that way, more power to you.
Either content yourself with manual centering, or improvise flush deadstops, using carved wood or plastic and glue. They don't have to be fancy or strong, since they don't take any load.
