Replace the 'x' in WooCommerce cart.php with text because 'x' is not helpfull at all for screenreader users. I give a extra class to the text so that it can be hidden with CSS for visual browsers, because I replace that link with Font Awesome icon using :before. See also: https://github.com/woothemes/woocommerce/issues/5725.

Unfortunately This code will remove two data attributes in the output data-product_id and data-product_sku.

You can do it using the action [woocommerce_before_cart_contents] to get the cart list in a global variable once before foreach begins and of course the main filter [woocommerce_cart_item_remove_link].

class THEME_SLUG_WooCommerce {

    private static $_instance = null;

    /**
     * The Cart items
     * @var array|null
     */
    public $cart_list = null;

    public static function instance() {

        if( is_null( self::$_instance ) ) {

            self::$_instance = new self;

            // Start Page Actions
            self::$_instance->init_actions();

        }

        return self::$_instance;

    }


    public function init_actions() {

        add_action( 'woocommerce_before_cart_contents', array( $this, '__before_cart' ) );
        add_action( 'woocommerce_before_mini_cart_contents', array( $this, '__before_cart' ) );

        add_filter( 'woocommerce_cart_item_remove_link', array( $this, '__table_cart_item_remove_link' ), 10, 2 );

    }

    public function __before_cart() {

        self::$_instance->cart_list = WC()->cart->get_cart();

    }

            return wp_kses_post( $output );
        }

        $cart_item = $cart[ $cart_item_key ];

        $_product = $cart_item['data'];

                    esc_attr( $cart_item_key ),
                    esc_attr( $_product->get_sku() ) ); 

        return wp_kses_post( $output );
