Yes, just create a new menu (the code below is for 4.1.x branch)

{if $active_modules.Whats_New}
      {capture name=menu_new}
          <a href="home.php?WhatsNew=Y">{$lng.lbl_wnmod_title}</a>
      {/capture}
      {include file="menu.tpl"  menu_title=$lng.lbl_wnmod_whatsnew menu_content=$smarty.capture.menu_new}
{/if}

and turn 'what's new' category off by commenting the line

$smarty->assign($var_name, $wn_cats);

(replace it with)

#$smarty->assign($var_name, $wn_cats);

in the file modules/Whats_New/categories.php
