No. Fringes should be set by users only.

My example is a simplification. There might be many more buffer-local
variables to set and the conclusive 'set-window-buffer' call to put them
into action might appear much later, maybe also in some other function.
The simplest approach should be to put an extra
(set-window-buffer nil (window-buffer))
right after the
(with-selected-window (window-normalize-window window t)
in 'window-max-chars-per-line'. But there's no right KEEP-MARGINS value
to pass here.
Maybe you should just say in the doc-string that if there are any
pending buffer-local changes, they should be applied before calling
'window-max-chars-per-line'.
