Does anyone have a method for removing headset bearing cups when they're butted up against the edge of this thicker portion of the headtube? I tried using my smallest punch to get these bearing cups out, but I just couldn't get it to work. I also tried using a thin screwdriver, but that didn't do any better.

The cups are very sturdy. Bang away. The only reason to remove them is for new paint. I just took a vintage Murray apart an the frame was factory painted with the cups in place. Yes, paint in the cup where the ball bearings roll. I used to think the Chinese invented using paint as bearing lube but the BMA5 were doing that long ago.

My reason to remove them is because I have a better bike that needs them.

I've got a Murray frame with painted bearing cups too. I don't know if I got those cups out...
 
I actually used @Kevin B's suggestion and used the biggest adjustable wrench I had handy to knock out the bearing cups. Worked like a charm! A few good whacks with the hammer, and they were both out! Thank you everyone for your advice! I now know what to do with hard-to-remove cups from now on.
