Yes, you can.

Alternatively you can use a task_group:

tbb::task_group g;
g.run(foo);
g.run(foo);

g.wait();

If you want to run it as often as you have CPU-cores, you can do it like this:

tbb::task_group g;

for(auto i = 0; i != tbb::tbb_thread::hardware_concurrency(); ++i) {
    g.run(foo);
}

g.wait();

Yes, nothing will stop you, but you're responsible for determining whether those actions will cause race conditions or concurrency issues that will blow up your program.
