Its more a difference/change in naming conventions over the millenniums rather than a difference in magical mechanisms.
I believe Renarin is Voidbinding in terms of definition, but Surgebinding in terms of mechanism.
Although with Renarin the infusion of a third "flavor(?)/layer(?)" of investiture into the Radiant bond seems to add Fortune to the underlying Surge combinations.
Basically everything "magical" on Roshar is Surgebinding but if it involves Odium in anyway then its Voidbinding.
