The fact that has Apple has more money than they know what to do with is the real factor for legal repercussions.
It's one thing to have theoretically defensible IP, and other thing entirely to actually be able to.
Assuming equal resources backing the legal teams, it would probably be sufficient that they are both forms of software, as all software trademarks are lumped together in the single category. There might be some sort of passing off action one way or another but it would be more likely to come from Apple than HealthKit.
There seems to be overlap between the Health app and Healthkit.com which I suppose is the real issue. Hard to tell if Healthkit truly got sherlocked though, because I can't tell what they do from their website past management software.
