It's not the fringe, it's space reserved for displaying the cursor
when there's no fringes.

No, but you can come very close if you use this instead:

  (fringe-mode '(1 . 1))

This will leave a 1-pixel fringes, but I very much doubt that those
pixels will be distinguishable from nothing at all.  The downside of
this setting is that the cursor will become barely visible in
full-width lines.

No, this is how Emacs lays out display when there are no fringes.
