Yes, but if you use <script src=foo /> with no closing tag, the rest
of the page will be eaten, since it will be inside the script tag and
scripts' contents don't get displayed. At least in some browsers.
Firefox 3.0 and 3.5 display this page with no title and no text:
<script src=foo />
Recentish WebKit does actually respect the self-closing part of the
<script> tag, and does display both the title and the text (but only
if the trailing / is present). I'm pretty sure Firefox is correct
here according to the current HTML 5 spec, and WebKit is wrong, but I
haven't actually looked. (Of course, the behavior in both cases
probably predates the spec.)

Because <style> and <script> were invented at different times by
different groups of people, I'd assume.

It wouldn't be unreasonable to introduce src="" for <style> for
consistency, and/or rel="script" for <link>.
