Can you swap one for the other?
Only partly. Most of oats's flavor molecules (127 of 166) are also found in barley, but barley has 226 that oats lacks. Oats gives you part of barley's character without most of its tartness. This compares flavor only; texture, moisture and the job each does in a dish matter too.
