You can, but be wary as they will work only in some dishes. While hard cheeses made with vegetable oil can be used in cooking like their fattier equivalents, reduced fat soft cheeses tend to perform poorly in cooking. In particularly, they should not be used for icings or dips as the process of stirring will break down the texture of the cheese and the finished produce will be disappointingly runny.
Reduced-fat soft cheeses can however, be used in recipes such as cheesecakes and mousses which contain several other ingredients, but remember to check the flavor level carefully as these cheeses have a less assertive flavor than their full-fat equivalents.
