No, there is no general discount on TER which would apply on multiple regions.
That said, about your Lyon-Marseille example, Illico discounts offered by Rhône-Alpes region explicitely mention that they are valid on that TER under some conditions. See e.g., Illico Annuel:
Conditions parcours interrégionaux :
- Vers Bourgogne, Franche-Comté et Provence-Alpes-Côte d’Azur
- Abonnements vendus en Rhône-Alpes et sur support papier (pas sur carte OùRA!)
- Billets avantages (réductions autres trajets) possibles uniquement sur les trajets en Rhône-Alpes
which translates as:
Conditions for interregional routes:
- To Burgundy, Franche-Comte and Provence-Alpes-Côte d’Azur
- Only for paper-based subscriptions sold in Rhône-Alpes (not on the OùRA railcard!)
- "Billets avantages" ([discount on trips not included in the subscription]) possible only on routes in Rhône-Alpes
