Νο you cannot do it with the latest versions of Smartphone Link and Google Maps or Apple Maps.
Only with very old versions was possible.

Android:
Latest version of Google Maps does not Share coordinates anymore, but only the exact adrress and a "short link" for PC Google Maps
Latest version of Smartphone Link does not Share a point on its (HERE) map with with Google Maps any more.
Latest version of Smartphone Link does not accept coordinates from another program.
I used OSMand Maps to mark a point and share it to Navigon Android and it was received OK as coordinates, but when I shared it to Smartphone Link, it just opened its Here map.

iPhone:
Same things, using both Google and Apple Maps, no transfer ability to Smartphone Link from both apps..
