I did not feel confident enough that I had recorded the faint outer satellite Leda on the images I took on my second run, posted above, so I went back to Run 01 and processed the 27 frames using PixInsight.
Pleasingly, the results were much more conclusive, and I now feel more confident that I managed to record the faint trail of Leda, a magnitude 20.068 satellite of Jupiter.
I obtained the positional data from the JPL Horizons website and plotted the calculated positions for the start/end times of the 27 frames I captured, and the fit was excellent.

I plotted the JPL data and when I overlay the results, there is a very good fit to the recorded trail. I also identified a couple of faint field stars, at mag. 20.01 and 20.08 to give me some confidence that I was reaching these fainter levels.
