I just tried it with my Unix v5 and v6, never touched the boot block
in either case.
v5: will not accept the kernel filename in a subdirectory.
v6: accepted the kernel filename in a subdirectory.

I don't know much about the other versions,

what's in the bootstrap (usually contained in block 0 of drive 0, at
least on older 11's). In V6, the bootstrap in block 0 prompts for a file
name, and when that is entered, it loads that file into memory and
starts it. (It doesn't have to be in the root directory, IIRC - I'm
pretty sure the bootstrap will accept full path names.)
I'm pretty sure that it didn't have the full namei() functionality, so all
files had to be in the root directory. Of course, I've been wrong
before...
We were constantly writing boot blocks to get the mostest out of the
leastest, so I suppose it was possible.
