The short answer is no. Reports to Facebook are completely anonymous.
With that being said, people aren't stupid and if they have a suspicion about you because you are the only other person in the picture (I don't know the full circumstance) then they can search your name and find your page that way.
There is nothing they can do to prove you were the one to report the picture. Online pictures are not "toys" as they can be there permanently even after you "delete" your account. If you do not want to be seen in that picture, you should definitely report the picture to have it taken down.
Best of luck
