All the answers are wrong.

Rebirth is pretty much meant for older units that getting a dokkan. The dokkan upgrades their stats,skills and adds new abilities which make them keep up with the current meta aka a rebirth as a new unit.

I can list you a bunch of units (str rage vegeta,int beerus, lr vegito blue) that has no fierce battle link, or their medals are from quest/story missions but has tur dokkan since day 1. Are they considered rebirths? Of course not. In fact lr vegito blue has STL link but he is a brand new unit with tur,lr dokkan.
