Can a Dead Indoor Palm Be Revived from Roots?

A potted palm is mostly dead but some roots are still green. Owner asks if roots can regenerate.

Possibility

If the top is cut back and watering is reduced to only when soil is very dry, there's a chance roots will send up new shoots in 2–3 months. Place in a sunny, out-of-sight spot to avoid overwatering. Likely cause of death: overwatering (standing water in saucer). Use a moisture meter ($10) to prevent recurrence.
