During an internship in 1986 I wrote C code for a machine with 10-bit bytes, the BBN C/70. It was a horrible experience, and the existence of the machine in the first place was due to a cosmic accident of the negative kind.

10-bit arithmetics are actually not uncommon on fpgas these days and are used in production in relatively modern applications.

10-bit C, however, ..........

How so? Arithmetic on FPGA usually use the minimum size that works, because any size over that will use more resources than needed.

9-bit bytes are pretty common in block RAM though, with the extra bit being used for either for ECC or user storage.
