Had Satoshi named it differently, Bitcoin would probably still be enjoying the success it has today, provided it won't be given too nuisance a name as BoobCoin or BeiberCoin. Bitcoin got its success from its features.
I don't think it would enjoy the sam success if it were named differently, even if it's not annoying sounding name. Probably we can get by with it given that it only takes acclimation to the names since it delivers what it does anyway.
The earliest people who believed in Bitcoin wasn't impressed by its name but by its features. They were enamored with the revolutionary technology not because it is called Bitcoin but because it offers properties never before seen from a currency. They've predicted a bright future for the cryptocurrency not by simply looking at its name but by going through the design detail by detail. Bitcoin remains to be the decentralized, transparent, censorship-resistant, permission-less technology even if it is called another name.
The name is immaterial. It's probably why Satoshi didn't even care to explain why he/she/they called the currency Bitcoin.
