Can you swap one for the other?
Only partly. Almost all of beetroot's flavor molecules (227 of 257) are also found in onion, but onion has 138 that beetroot lacks. Beetroot 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.
