I have done that with my 1933 Chev. This was a negative ground system and when I connected the two together it was a very brief connection. Its somewhat risky because the jumper cables will act as a resister that changes the 12 volts to 6 volts.
I did the "jump" when I was 18 years old and was "indestructible". Today I would use a battery charger made for 6 volts.

Yes on the cables, it might make sense to intentionally carry cheap smaller gauge jumper cables to add some resistance.
But I'm asking in the context of being on the road, not the garage. I drive my Model A to the hardware store, it's a little balky starting,or maybe I left those oh so bright headlights on by mistake, and I run the battery down. Do I jump it to get going again? I'm leaning towards yes.
