Closer. 36 bit doesn't work, but 7 at least completes the transfer.

?Bad format for EXE file directory

.run hello.exe

Hello, world!!!

EXIT

.

So the file doesn't get back to TOPS-10 correctly, but at least the
transfer happens this time. 8bit-to-bit doesn't work at all.
The syntax on Linux is

set file bytesize N

versus

set file byte-size N

for TOPS-10. C-Kermit only will take 7 or 8, while K10 shows:

36-bit		7-bit		8-bit		auto-byte	eight-bit
seven-bit	thirty-six-bit

Neither 36 to 7 nor 36 to 8 gets a file. Only 7-to-7 does.  You can see
there's stuff in the file, but it's corrupted in some way.

Any other Kermit I've used is fine. Just TOPS-10 is the challenge.
