Can you swap one for the other?

Only partly. Most of leek's flavor molecules (218 of 261) are also found in basil, but basil has 156 that leek lacks. Leek gives you part of basil's character without most of its herbal side. This compares flavor only; texture, moisture and the job each does in a dish matter too.
