No I'm pretty sure Naruto summoned the toad boss with his own chakra. At the end, right before his final head butt attack on Gaara, he summons the kyuubi chakra, and you can see that red chakra STARTING to flow through his coils. I doubt Kyuubi will be bothered to give him chakra twice, or that Naruto would NEED kyuubi to give him more power a second time.
