No, `TeX-fold-mode' doesn't work for sectioning commands. But for those
you can use `outline-minor-mode'. AUCTeX already sets that up to work
with LaTeX documents. Have a look at the emacs docs (info
"(emacs)Outline Mode").
For me, the standard outline-minor-mode keys (C-c @ ...) are too hard to
remember and inconvenient. So I have some additional code that makes
TAB [or whatever key you like] on a outline heading (like \section{foo}
in a LaTeX doc) cycle through the states "collapsed", "shown with
children collapsed", and "everything shown".

(defmacro define-context-key (keymap key dispatch)
"Define KEY in KEYMAP to execute according to DISPATCH.
DISPATCH is a form that is evaluated and should return the
command to be executed.
If DISPATCH returns nil, then the command normally bound to KEY
will be executed.
Example:
(define-context-key hs-minor-mode-map
(kbd \"<C-tab>\")
(cond
((not (hs-already-hidden-p))
'hs-hide-block)
((hs-already-hidden-p)
'hs-show-block)))
This will make <C-tab> show a hidden block. If the block is
shown, then it'll be hidden."
`(define-key ,keymap ,key
`(menu-item "context-key" ignore
:filter ,(lambda (&optional ignored)
,dispatch))))
(defun th-outline-context-p ()
"Non-nil if `point' is on an outline-heading."
(save-excursion
(goto-char (line-beginning-position))
(looking-at outline-regexp)))
(define-context-key outline-minor-mode-map
(kbd "TAB")
(when (th-outline-context-p)
'org-cycle))

Bye,
