Looks like I found a solution for anyone who wants to have JUST the tags be the common link for related products.

I edited the file /woocommerce/classes/class-wc-products.php

This is pasted starting at line 1192, I commented out a couple of lines.

// Related products are found from category and tag
		$tags_array = array(0);
		/* $cats_array = array(0); */ /* <-- commented out this line */

		// Get tags
		$terms = wp_get_post_terms($this->id, 'product_tag');
		foreach ($terms as $term) $tags_array[] = $term->term_id;

		// Get categories
		/* $terms = wp_get_post_terms($this->id, 'product_cat');
		foreach ($terms as $term) $cats_array[] = $term->term_id; */  /* <-- and commented out this line */

		// Don't bother if none are set
		if ( sizeof($cats_array)==1 && sizeof($tags_array)==1 ) return array();

If anyone knows how to make what I’ve done into a line of code to copy to my own theme’s functions.php that would be great since now if I upgrade, I’ll have to manually edit this out again.
