Logically, the ThinkPad L13 is the direct successor of the ThinkPad L390, while the ThinkPad L13 Yoga is the follow-up to the ThinkPad L390 Yoga.
On the flip-side, it seems like the ThinkPad L13 line loses it's upgradeable RAM capability, as Lenovo will offer 16 GB of soldered memory as the maximum amount of RAM. The older ThinkPad L390 models could feature up to 64 GB of RAM, thanks to the two RAM slots.
