Can you swap one for the other?

Only partly. Almost all of arrowroot's flavor molecules (203 of 205) are also found in onion, but onion has 162 that arrowroot lacks. Arrowroot 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.
