Maybe, it can be possible, but there still are a lot of flaws. I mean, before the Ten-Tails attacked, Hagoromo/Hamura were confronting Kaguya, and they clearly realised it. Even Gamamaru mentioned that they'd have to fight her, not Shinju, but her. Also, in the anime Hag/Ham fought Ten-Tails and Kaguya as separate beings, which must include Kaguya battling them as well (assuming that Kaguya didn't just watch the fight from afar, and it's more than assumption, since it ended up in Hag/Ham using SP-CH on her instead of Ten-Tails). Moreover, the Ten-Tails basically faded away after Kaguya's sealing, so it must've been easy for Hagoromo to conclude that it was controlled by Kaguya all the way.
