Yes you can compost grass that has been teated with a weed killer. Wether weed kill or some other product keep the product in mind when you use the compost. depending on the product you may not want to use it in your vegtable garden. In your case this would be great to use weed killer compost on the lawn. As time goes by most of any added product will leach out of the compost but I would still use care were the compost gets used. I use weed kill and ferterlizer on my lawn and compost the clippings. I use most of the compost on the lawn and in the flower garder with no know problems.
