Can you swap one for the other?
Only partly. Almost all of pistachio's flavor molecules (210 of 239) are also found in onion, but onion has 155 that pistachio lacks. Pistachio gives you part of onion's character without most of its sulfurous side. This compares flavor only; texture, moisture and the job each does in a dish matter too.
