No.
''Thread'' or ''Task'' are merely metaphors for quasi-concurrent execution in the context of an OS. Threads/task are objects handled by the OS, thus require an OS.
But yes, you can achieve such a virtually concurrent execution by other means. The management of those ''threads'' (creation/termination, scheduling, resource allocation/arbitration, communication) is then totally up to you.
Most commonly, it starts with a periodic timer interrupt.
