Could we say that, "I wouldn't know" and "How should I know?" have the same meaning?
Can we use them interchangeably?

They are similar in meaning, but vastly different in politeness.

From most apologetic to most insulting...

I'm sorry, I don't know

I wouldn't know

How should I know?

The first would be acceptable in polite society, the last might be worthy of a punch in the face.
