No.
The easiest way to see if it's correct is to drop the first two words.
Would you say? Him ate the sandwich?
Of course not. But you would say: He ate the sandwich.
Therefore the correct sentence is:
Martha and he ate the sandwich.
Martha and he are the subjects. Since him is an object pronoun, we can't use it as a subject.
Is the following a correct sentence:
Martha and him ate the sandwich.
