Can you swap one for the other?
No. Onion and peanut oil are different kinds of food, so neither stands in for the other, whatever molecules they share. Treat them as partners, not stand-ins. This compares flavor only; texture, moisture and the job each does in a dish matter too.

What they have in common
More than half of peanut oil's flavor molecules (36 of 67) also occur in onion. Among the shared key aromas are acetic acid (sour, vinegar) and 2-methylbutyraldehyde (malty, chocolate). Most of what they share is background chemistry many foods carry, so the overlap does little for the smell. Shared chemistry is a reason to try a pair, not a promise that it works on the plate.
