Yes of course. The tarball is still needed. This is a development feature.
- Select the base kernel version in platformconfig (this will be downloaded)
- work on the kernel tree in local_src/kernel.<platform>
- export the final patches and remove local_src/kernel.<platform>

For something permanent it _may_ work to overwrite KERNEL_URL:

$ cat rules/post/fixup.make
KERNEL_URL := file://$(PTXDIST_WORKSPACE)/local_src/my-special-kernel
$

But I'm not sure if that really works for the kernel.

Michael
