Compare two lists, item by item, using linq

I want to compare two lists, item by item. How can I express the following code using linq?

bool result = true;
var list1 = new List<int> { 10, 20, 30, 40 };
var list2 = new List<int> { 10, 20, 30, 40 };
for (int index = 0; index < list1.Count(); index++)
{
   result &= list1[index] == list2[index];
}

You can use SequenceEqual:

Determines whether two sequences are equal by comparing the elements by using the default equality comparer for their type.

Example:

bool result = list1.SequenceEqual(list2);
