It's entirely possible. Round the right hand side of the compound, towards the rear, you can get your horse to jump over one of the small columns between the metal fence sections (there's a video on Youtube, looks like PC but I just did it on the 360 so it definitely works...). Now you can explore the entire area apart from the entrance courtyard and complete Diplomatic Immunity without ever meeting Malborn or giving up your gear. You'll need to wooden plate into the party room if you want to but there's nothing to do here, if you get the dossiers etc from Elenwen's solar the quest will just progress as if you followed all the steps, Malborn appears in the dungeon and tells you the Thalmor will be hunting him for the rest of his life etc. Literally just done this so there's no telling if it breaks the quest or anything yet but I'll let you know
