I believe you can include it. On one hand having examples of leadership within same-sector or same-role might be preferable when applying in order to tailor your CV to the employer. On the other hand, that obviously is only possible when you worked in a similar role before, which for applicants to consulting is mostly not the case.
In addition, it is great to demonstrate leadership within a broader set of contexts and challenges.
Just make sure that including that description in CV does not come at the price of removing more recent of closer experience to the role, also in the outlook of an optimal structure and lenght.
