Kaguya was everything her sons wer and more so I don't see why she wouldnt have the potential to get the Tenseigan.

Kaguya also wasn't retarded. She lacked combat experience. During her time she didn't have to be particularly good with her powers, she just had to have them.

She was stronger than Madara though. She had more chakra. During the short time that he had both Rinnegan, Team 7 was able to get in his face while Kaguya pretty much bitch slapped Sasukes Susanoo away.
