No. Now that the plot-armored ones are out of the spotlight let the others have some time and no, his magic can retrogress anyone. What does Wendy being younger have to do with it? She will be turned even younger like to the time when she first met Edo-Jellal. Besides he commented that he turns them back to their "memory" as a child so unless Wendy magically(lol) erased her time as a kid she would also be affected. But more on this in the next chapter when the guy explains the rules of his magic.
