Hello,
you can modify the
themes/classic/templates/checkout/_partials/order-confirmation-table.tpl
this way
{*if $add_product_link*}<a href="{Context::getContext()->link->getProductLink($product)}" target="_blank">{*/if*}
<span>{$product.name}</span>
{*if $add_product_link*}</a>{*/if*}
to get the Product Name linking to the Product.
Maybe there are other ways or variables but its a way to make it work
