Answer
Can Starlink use the coaxial cable from my old satellite TV dish?
No direct substitution should be assumed. Starlink's documented kits use their specified power and data cabling; a satellite TV coaxial cable is a different connection and does not become compatible by adding a simple plug adapter.
You may be able to reuse a suitable cable route or building entry after an installer checks its size, condition and sealing. That is different from reusing the cable itself. Plan for the Starlink connector dimensions as well as the cable thickness.
Our practical recommendation is to show the old route to the installer and ask for an itemised plan. Do not cut the new cable to squeeze it through an existing hole.
An existing coax network may support separate networking products designed for that purpose, but that would be a distinct LAN design. It should not be confused with the powered connection between the Starlink dish and its supplied equipment.
