Nope, no worries doing so.
Some snakes may not choose to eat during shed, and some may. I have seen both.
Here's a funny story. Once I went on vacation, came back, and then fed everyone. My 99 albino Nelson milk male was fed a decent sized meal. Little did I know he had gone into the blue while I was gone, and decided to start shedding right after I fed him!!
I come back in the room a few minutes later, and there he is straining and straining to get that unraveling/unrolling skin over the big food bulge, looking up at me as if to say.." What in the living.........hey buddy..you wanna give me some help here? I ain't got all day!! "
I carefully helped him get the skin over the food lump. He then was fine, and went and crashed afterwards.
