I wouldn't remove it, you will will be prone to errors. But you can edit how it appears by going to system admin>templates.
Make a clone of the default template, then edit your clone. In the cloned copy, you can edit system_redirect.html in the system files.
An edited redirect an look really nice once it's changed. Theme developers should included a new redirect file, but thats just an opinion and an option I would use if I were releaseing themes. (I'm not knocking theme devs, it's easily overlooked!)
*EDIT*
Here is a code snip I use for my site:
<{$sitename}> <{$message}>
<{$lang_ifnotreload}>
*Shoves the dirty code under the carpet as the guests walk in*
Don't mind the mess...
Hope you find it useful
