No. A kernel is a __global__ function, which means it can only be called on host and executed on device.

If your GPU compute capability supports dynamic parallelism, you can call kernels from within kernels.

Don't think you may call __global__ function() again, because you are now in device, the '__global__ function()' can only be called from host.

Someone said we can do that with certain CUDA version. I am not sure if that is ture or not.
