My question is, can a dying battery cause the soft clipping?  For example, will a certain mic not clip at all at a given spl when given the right amount of power, but soft clip at the same spl when underpowered (e.g., from a dying battery)?

Yes.  It's very common for the levels at which the max SPL clipping limit occurs, and the somewhat lower levels at which any particular measured distortion threshold is encountered, to decrease as the microphone is starved for power.

Any insight into the technical reasons for this?

I assume that one can't tell whether the cause is a dying battery or a mic that's overloaded, at least in terms of soft clipping, purely from a picture of a waveform like the one in the first post.  Is that correct?

I can't, but educated guesses can be made.

Microphones are like people.  If you aren't well fed you can't do hard work well.  If you aren't fed at all you'll stop working all together.
