Yes, but it goes a lot deeper than simply being able to eat on land. The critical adaptations for terrestrial existence would be as follows.
1. Ability to breathe air for indefinite periods (thorough modified gills, presumably).
This would enable longer foraging bouts on land.
2. Internal fertilization. (A whole host of consequences arise from this one). Without this adaptation, vertebrates would be still tied to the marine environment for reproduction (recall fish and amphibians fertilize externally).
3. Eggs able to withstand desiccation in terrestrial habitats.
An alternative to this was adopted by most vertebrates - increased gestation periods with live birth of altricial young, followed later on by live birth of precocial young in some larger vertebrates.
