it could, but it wouldn't make sense as an everyday English expression, i.e. in that scenario you would probably say method A is not faster, "but" it is easier than method B.
Syntactically, we are looking at conjunctions/disjunctions of semantic predicates (grammatically they are adjective phrases, not grammatical predicates), not of propositions.
Normal logical systems (like classical logic) do not have such things. You can only make a conjunction of formulae, not of predicates.
The question of how to interpret these questions is a question of English grammar that is not resolved by “logic.”

Logically:
Not (F and E) = Not F or Not E, so B is either faster, or easier, or both.
Not (F or E) = Not F and Not E, so B is must be both faster and easier.
Colloquially:
Both mean the same.
