About IEnumerable<T> isn't an enough reason to prove what you said, here's my demo:
public class A{public int Number{get;set;}}
//Sample db contents
List<A> a = new List<A> { new A { Number = 1 }, new A { Number = 2 } };
//Fetch an interface
IEnumerable<A> r = from i in a select i;
//Change number
r.First().Number = 2;
Console.WriteLine(a[0].Number);
