Good question. Can it? Probably, and only context can tell them apart, I suppose.
I'm wondering this too. It would seem to be redundant when followed by "zo... als"- it was not included in a prior similar exercise "zo snel als".
You need to use the adverb "well" in this sentence instead of the adjective "good," but "she" should be accepted as the subject of the understood verb "can."
But in everyday speech sounds like something from a period drama! Sometimes grammatically correct does not match everyday usage. So "....as well as she" sounds really old fashioned. Strangely, changing to "...as well as she can" sounds less old fashioned. "As well as her" may seem ungrammatical but is a usual form. Strange language - english!
