That largely depends on how you look at things. If you look at it from the perspective that the time line was "fixed," then there would be no way for her to have those memories, as she never experienced them in the first place. If you look at it from the perspective that what Kyon experienced is what really happened during the three day period and everyone else has false memories of those days, then it's possible she remembers those events.
In an effort to make things short: Probably not.
