Whether it can or can't, I'd say Neji's defeat was largely due to overconfidence. He felt that a goofy loser like Naruto could never defeat a genius like him, so he let his guard down. Remember that both Neji and Tenten assumed the fight was already over (An American expression would be, "It's all over but the cryin'.") until Naruto struck the final blow.
