I would honestly be surprised if she doesn't know. Not because anyone told her, but because Akira is absolutely brilliant and was involved in some of the investigation concerning Kaneki. So she should have been able to connect the dots, regardless of whether she was told the truth about him or not. He looks like the missing college student they were investigating, was made a half-Ghoul by Dr. Kanou, has amnesia and appeared in the months following Arima "eradicating" Centipede, and has the same kagune as Eyepatch/Centipede.
