答
Yes you can since Wordpress is written in PHP, and PHP allows you to use whatever database you want.

Late to the party, but if you're willing to add stuff to the wp-includes/wp-db.php file you can query those other databases using the $wpdb object.
Specifically, you need to add a var:
/**
* WordPress Term Relationships table
*
* @since 2.3.0
* @access public
* @var string
*/
var $term_relationships;
and add your database name to this:
var $tables = array('users', 'usermeta', 'posts', 'categories', 'post2cat', 'comments', 'links', 'link2cat', 'options','postmeta', 'terms', 'term_taxonomy', 'term_relationships');
