Yes, in the theme you can check the comment's status and if the comment is posted by the
current user.
Something like this, in a loop of all the comments:
$commenter= User::commenter();
if ($comment->email == $commenter['email'] && $comment->status == Comment::STATUS_UNAPPROVED) {
echo "Your comment is in moderation.";
}
