Dell has not yet officially announced any Renoir-based laptops, and rumor has it that we will not only see Renoir-based laptops, but models powered by the Renoir successor codenamed Cezanne, as well, next year. Cezanne will get a Navi23-based iGPU and is supposed to be AMD's answer to Intel's Tiger Lake-H. Dell's Cezanne-H laptops will additionally feature high-quality FHD and QHD displays with high refresh rates.
