I wouldn’t recommend pouring it on a lawn unless you’re handling very small amounts of near room temp grease or you know you have a lawn that has properties good for filtration. Even then I’d avoid it because dogs or animals might try to tear up the lawn.
If you have a fenced compost pile with proper cover material it shouldn’t be a problem as long as you have enough cover material (such as straw or wood chips) to absorb the grease.
