Hmm. I just tried querying a table that was not in the model and, providing you have a C# class that matches the names/types of the returned columns, it seems to work. eg:
        public class Carriers
        {
            public string Name { get; set; }
            public string DepProv { get; set; }
        }
then this is OK:
var yyy = PGD.Database.SqlQuery<Carriers>("SELECT Name,DepProv FROM dbo.Carriers").ToList();
