That is, is it possible, by e.g. passing some parameter to StartNew(), to ma

Yes, you can pretty much do that using custom task schedulers.

internal class MyScheduler : TaskScheduler
{
    protected override IEnumerable GetScheduledTasks()
    {
        return Enumerable.Empty();
    }

    protected override void QueueTask(Task task)
    {
        base.TryExecuteTask(task);
    }

    protected override bool TryExecuteTaskInline(Task task, bool taskWasPreviouslyQueued)
    {
        base.TryExecuteTask(task);
        return true;
    }
}

static void Main(string[] args)
{
    Console.WriteLine(Thread.CurrentThread.ManagedThreadId + " Main");

    Task.Factory.StartNew(() => ThisShouldBeExecutedSynchronously(), CancellationToken.None, TaskCreationOptions.None, new MyScheduler());
}
