Yes, the user agent can decide how best to treat icons based on the
available size. Where the width and height help is to establish the viewport
(the window in which the SVG will be rendered).  So, if an SVG declares
itself to be 1000 by 1000px (<svg width="1000" height="1000" ...>), but the
width and height of the icon both say 100 pixels, then the rendered
representation of the SVG will simply get clipped because it won't fit in
the 100 by 100 viewport.
