If there is any chance at all, under any circumstances, that the wire could be pinched or shorted against chassis metal, then you need a fuse not only where you're pointing but also within a few inches of the second battery's positive terminal.
If that wire gets grounded, and there's no fuse, then EITHER battery can easily provide enough current to overheat the wire and start a car-be-cue. The purpose of a fuse is to protect the wire if it gets shorted, and when a wire gets destroyed by over-current, it takes along whatever's next to it.
If the two batteries are side-by-side and the wire run is just a few inches and doesn't pass vehicle metal, then you don't need a fuse. If one battery is in the trunk and the other is in the engine compartment, you NEED two fuses on that wire. A single fuse would do you no good at all; the wire needs to be protected at each power source (ie, battery).

No! This will be of no use as the other battery is still making the circuit. The other fuse should be sufficient if you use the correct ampage fuse.

No but running two batteries may require a larger alternator

No...but remember, in parallel, voltage remains the same, but amperage doubles.
