Based on playing with the search a bit more since the changes, this can include hyphenated names such as Deutsche-Grammophon (even though I know this is a poor example because they do not hyphenate their name).
Sadly, the best that I can come up with (off of the top of my head) is ‘orthophonic’, which is a measly 11 characters.
Can anyone come up with something longer than 20 characters that is a real word or name? (And if not, please post your best attempts at beating my 11-letter entry.)
