There is overlap based on both projects being a general purpose Drupal administration CLI tool. Drush has more features, due to its age, but Drupal Console has some new features due to its more modern design.
It might help to read Ten things you need to know about Drupal Console coming from Ray Saltini of FFW (the company supporting the lead developer Jesus Olivas of Drupal Console), & Drush and the Drupal Console with Drupal 8 from Greg Anderson (one of the maintainers of Drush).
To explicitly answer the question, maybe. If you're wondering which should I use?, the answer is both for the time being. Perhaps Drupal Console will eclipse Drush, but right now both have useful feature sets for administering your Drupal site.
