Yes. But you have to integrate that page with vBulletin first. Adding these lines at the top of your custom 404 page will do the trick:

<?php
$forumpath = '/home/youraccountname/public_html/forum';
chdir($forumpath);
require_once('./global.php');
exec_shut_down();
?>

Edit the $forumpath with config.php's $config['Misc']['forumpath'] = setting.
