Yes, it should work as long as you inform JSON.Net that you want to use TypeNameHandling.All and use appropriate casting. The following works in my project:

 public class MembaseJsonSerializer
 {
     private IContractResolver resolver;

     public MembaseJsonSerializer(IContractResolver resolver)
     {
         this.resolver = resolver; 
     }


    public R FromJson(object json)
    {
        if (typeof(T).IsAssignableFrom(typeof(R)))
        {
            object res = JsonConvert.DeserializeObject(json.ToString(), new JsonSerializerSettings() { 
                ContractResolver = resolver, 
                TypeNameHandling = TypeNameHandling.All 
            });
            return (R)res;
        }
        throw new NotImplementedException("Type is not assignable.");
    }

    public string ToJson(object obj)
    {
        if (typeof(T).IsAssignableFrom(obj.GetType()))
        {
            string json = JsonConvert.SerializeObject(obj, Formatting.None, new JsonSerializerSettings()  { 
                ContractResolver = resolver, 
                TypeNameHandling = TypeNameHandling.All 
            });
            return json; 
        }
        throw new NotImplementedException("Type is not assignable.");
    }
 }

Where T is the base class and R is the sub class.
