By number of acres cultivated, sure. By number of acres that have produce runoff of fertilizers and other byproducts into a major waterway, I doubt it. Also "lawn" doesn't mean grass. There are many alternatives to grass. For my backyard I discovered so long as I aggressively remove vines, shrubs, and saplings during the spring growth my backyard is otherwise maintenance free. As a bonus I get 9 ft tall sunflowers for part of the year as well.

I think the spectral imaging used to support this does collect all mown grass into turf. I think it can only distinguish tall grasses like wheat and maize from lawn. IIRC, you avoid certain times of year so that all short grass is an effect of landscaping.
