In short, no.
In longer, there's data in there that could be used for steganographic
purposes. If you don't setup your GIT_AUTHOR_EMAIL properly, perhaps
your machine(s) hostname(s) will be in the commit message. Whatever
timezone your machines are set to will influence the date field(s) in
commits.
If you are worried, take a look at raw objects in your repository to
see what is recorded:
git show --format=raw <some-git-object e.g. HEAD>
