Some behavioral modifications (e.g. a program of exercise) are widely supposed to do better than nothing - would something along these lines serve as a useful placebo?

That may be be difficult to test. Normally we introduce controls for 'placebo effects'. How are we supposed to control for "stuff that actually works"?

Tangential: positive controls are common in e.g. biology experiments, where the efficacy of the experiment to detect an actual effect can be in doubt. (This won't be the case in treating depression, where successful treatment can be detected by asking the patient.)
