I assume this is because you are having difficulty engaging the center pin of the Schraeder valve to pressurize the tire.
But, why would a valve stem be produced that was 0.015" too long?
I suspect that the pin on the valve itself, or the pin on your chuck may be the real issue (assuming the tire is hard to fill).
OR...
The valve is threaded 'in too far'... (if that is even possible).
To answer your question, I cannot see any reason that shaving off 0.015" would cause you any issues.

Yes. But this isn't something you'll accomplish in your garage with std hand tools

At 0.015, run it.. Heck if going to higher lift cams it may be good.. 0.050 might be an issue.. Really need to know what heads and valves..
BTW sometimes you can get shorter valves. AVnV makes a 1.900 intake that is 0.040 shorter than stock. It allows for sinking of the valve into the head to get valve to valve clearance..
You can also use corrected geometry rockers..

The way it's presented, I was thinking tire valve stem also.

I used to grind valves when I worked in a machine shop. Part of the process was grinding the tip of the stem to make it flat again. It can be done but not with the valve in the head.
I'm not familiar enough with these engines to say what will or won't work. .015" isn't much but specs are there for a reason.
I've done some shady **** with a buffing disc on die grinder on large diesel engines. Harley engines seem too delicate for that kind of thing.

It worked well. I can't tell anything has been ground off by looking at it and if I use a machinist's square and hold it up to the light, it's as squarely cut as the valve I did nothing to.
