It is not. The naming resemblance is strictly coincidental :)
BTW, it also appears there is an active US trademark (#78010053) for "centrifuge" in the computer database context. Isn't that an issue, too?
I started doing that after having to go through two iterations of renaming a project after finding out the old name was somehow encumbered... of course after we had already used it in front of other people; it was very embarrassing.
Still, do keep in mind that it's not the name of a product offering - it's solely an internal name for the technology.
