Combine one action and one filter

the filter function must be inside the action function, because if it isnt it is not recognize. So I think. At least with variables is like this.

add_action( 'woocommerce_before_checkout_form', 'add_checkout_error', 9 );
function add_checkout_error() {
    wc_print_notice( __( 'An error message.', 'woocommerce' ), 'error' );
    add_filter('woocommerce_order_button_html', 'remove_order_button_html' );
    function remove_order_button_html( $button ) {
            $button = '';
            return $button;
    }
}
