No, I think not. The expression on the left side can include only the local URL-path, not the domain. Therefore mod_alias directives cannot do what you appear to want to do here. Use mod_rewrite:

RewriteCond %{HTTP_HOST} ^([^.]+\.)?old-domain\.com
RewriteRule (.*) http://%1new-domain.com/$1 [R=301,L]

This assumes that you've got other working mod_rewrite code, and so have the required 'set-up' directives (Options +FollowSymLinks" and "RewriteEngine on") in your file.
