Yes, from published recipes using potassium ferricyanide and sodium thiosulfate, but handling these chemicals requires proper safety knowledge and precautions.
Farmer's reducer is a specific, controlled formula that acts on metallic silver. Common household bleaches (chlorine-based) act differently and would destroy a photographic image.
It is named after Howard Farmer, a British photographer and scientist who developed and popularized the formula in the late 19th century.
