The 35-year-old also risked receiving punishment from the Football Association by claiming that referee Michael Oliver made a "disgusting decision" to award the penalty.
"To call a player a cheat is totally out of order because there was contact there," Bowen told Radio Wales.
"Is Moses trying to make the best of a situation? Yes. Was it harsh on Swansea? Yes. Was the decision a poor one? Possibly yes.
"My definition of cheating is if a player goes into the area and he's not touched, if there's no contact and he goes down he's a cheat."
Moses joined Stoke on loan from Chelsea in the summer.
