Here’s showrunner Jac Schaeffer talking to EW about it:

“There were early conversations [about Hulkling],” Schaeffer said. “[Eddie] was originally called Teddy because we were looking at the artwork and thinking about that. That was a Marvel decision to not have him be Hulkling for the purposes of our show. Within our show, he is not Hulkling…but we pivoted to Eddie because he is named after a person that is important to the writers’ room. It wasn’t sort of teasing the fans, it was one of those lovely tributes to somebody who matters to us.”
