Can you swap one for the other?
Only partly. Most of tarragon's flavor molecules (213 of 270) are also found in onion, but onion has 152 that tarragon lacks. Tarragon 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.
