Good news! It's definitely possible. Deleveled has happened to many people. Even myself included when I thought I had my Xp off and wanted to test something on my 85 twink back in the day and it hit 86 mid content and I instantly Altf4'd out of the game and hit up blizz. He said he noticed I logged out immediately after doing so and never logged back in that toon till the ticket was answered so he was happy to delevel for me.
