Answer
No — a Lobby itself can't be displayed or embedded on an external page outside of IFS. To get similar real-time data shown on an external page like an intranet dashboard, the practical approach is to extract the underlying data through an integration platform (such as Boomi, if you're already using one) and build a separate dashboard (for example, an HTML5 page) on the external system using that extracted data, rather than trying to surface the Lobby component itself outside of IFS.
