Yes.

Yes.
"Edit an ISO image" comprises the following steps.
1. Mount the ISO image[*].
2. Copy the tree of files to a read-write filesystem.
3. Change the files in the read-write filesystem.
4. Create a new ISO image from the read-write filesystem.
[*] IIRC, there are utilities that allow you to combine steps 1-2 into
a single step: "Extract files from ISO image into a read-write
filesystem". But, I can't ever remember how to do that, so I
just do the two steps.
