Well, he is! He doesn't have to be in Wonderland being ignored or dominated by his wife, the Queen of Hearts. I mean the husband of the queen is the king, and Henry has similar characteristics of the King of Hearts.

Frome Sparknotes: The King of Hearts - The coruler of Wonderland. The King is ineffectual and generally unlikeable, but lacks the Queen’s ruthlessness and undoes her orders of execution.

Well, Henry didn't do the undoing of executions, but then again the QoH didn't take people's hearts in the book.

Like the Red King, he was a bit more subtle. I would have guessed the White King simply because he was wearing white, but then they mentioned he was the Red King.

Henry isn't directly based on him, but is definitely an allusion to. Most could see when Regina's parents both showed up, that they would definitely be the King and Queen of Hearts if Cora was indeed Queen of Hearts.
