The 'c' in coreboot is actually intended to be lowercase, as "coreboot" is the trademark (https://trademarks.justia.com/869/60/coreboot-86960637.html).
The reason I submitted the change was to make it easier to read - while I was reading the documentation, I had to reparse the sentence, to find it had ended.
IANAL, but it doesn't seem reasonable lowercase 'c' would be needed for trademark purposes, more likely a consistent branding preference. If it is what you prefer, it is your prerogative.

Adidas has a lowercase trademark and seems almost consistent on not capitalizing its name - often by using all lowercase or all uppercase throughout:

Web search shows capitalized name on their site, but I had to view source to actually see it on a page:

Secondary sources like the press and wikipedia don't seem to care about Adidas lowercase preference, at all:
