In the current version, no — suspending a customer only sets that one customer's own Active/Inactive status. Deactivating an account manager on their profile (or via the Active toggle on the customer list) does not touch the account-member link or the suspension status of their linked members, and deactivating a member does not affect the manager or any other members. Each linked account is suspended and reactivated independently from Customers > edit customer > Active toggle.

In the current version, this is inferred from the absence of any cascading logic between a customer's suspension flag and their account-member links; treat it as the current behavior rather than a documented design.
