Sure. Fanfiction allows for all kinds of wild combinations. Naruto using Edo Tensei in a Fairy Tail fanfic could be really exciting. Think about it: the Edo Tensei in Naruto is used to bring back the dead. In Fairy Tail, there are many powerful and beloved characters who have died. If Naruto were to use this jutsu in the Fairy Tail world, he could bring back some of those characters, like Igneel or even some of the guild founders. This would change the power dynamics in the Fairy Tail world and create new relationships and story arcs. It could also lead to some great character development as the revived characters interact with the existing ones and Naruto has to deal with the consequences of using such a powerful and somewhat unethical jutsu in a new world.
Yes, in fanfiction, the author has the creative freedom to make Naruto use Edo Tensei in the Fairy Tail universe. It's a cool crossover concept that can lead to some interesting storylines.
