Can an icon button label a field by itself?

Hello everyone,

I was reading over the Technique G167: Using an adjacent button to label the purpose of a field. I noticed that each example for the button, the button contained text. Therefore, I was wondering if a button who's only content is an icon, like a magnifying glass for "Search", would be sufficient for this technique?

Here is a code example:
<input type="text" name="search" id="search">
<button type="submit" aria-label="Search"><i class="search"></i></button>
