No, it’s a different jutsu, Tobirama himself says so (chapter 642 page 4). Juubi Jinchuuriki use it on both themselves (defensively) and Truth Seeking Orbs (defensively and offensively). If ordinary ninjutsu worked on JJ then Tobirama wouldn’t have noted that Senjutsu is effective against Obito. Also, Obito couldn’t neutralise ninjutsu in his uncontrolled state, as evident by Hiruzen not dying when he got hit by TSO.
