I believe it's as simple as "disabling" it an admin side and then linking to products in it. If you want to link to the whole category, you'll need to keep it enabled and change this:

<font class=CategoriesList>{ $categories[cat_num].category_name|escape }</font>

to:

{if $categories[cat_num].categoryid ne freecatid}
<font class=CategoriesList>{ $categories[cat_num].category_name|escape }</font>
{/if}

and change freecatid with what ever categoryid number the free category is.

Hope that helps!
