Comment (by TJNowell):

 If you do not create the variables at the top of `kses.php` with your
 custom values, yes!

 {{{
 /**
  * Specifies the default allowable HTML tags.
  *
  * Using `CUSTOM_TAGS` is not recommended and should be considered
 deprecated. The
  * {@see 'wp_kses_allowed_html'} filter is more powerful and supplies
 context.
  *
  * @see wp_kses_allowed_html()
  * @since 1.2.0
  *
  * @var array[]|false Array of default allowable HTML tags, or false to
 use the defaults.
  */
 if ( ! defined( 'CUSTOM_TAGS' ) ) {
         define( 'CUSTOM_TAGS', false );
 }
 }}}

 I'd suggest using the wp_kses_allowed_html filter as the documentation
 suggests.
