I have a blog that has a custom post type article, and the link is http://example.com/article/lorem-ipsum.

How can I use add_rewrite_rule to add a new link style to the same post http://example.com/article/lorem-ipsum/readers in such a way that the part readers add a GET parameter &showReaders=true to the page http://example.com/article/lorem-ipsum.

You want to use the add_rewrite_endpoint since what you are concerned with is at the end of the URL.

function wpseo331941_reader_endpoint() {
    add_rewrite_endpoint('readers', EP_PERMALINK | EP_PAGES);
add_action('init', 'wpseo331941_reader_endpoint', 10, 0);
//When you want to check if the 'readers' is being used
if ( false !== get_query_var('readers', false) ){

Note that the false !== has to be present, because your query var "readers" will have an empty string as its value.
