I've never used that functionality myself but, from what I can see, I'd say that the answer is no. My immediate thought was that you would Remove an entry from the Entries collection but it is read-only. I'd say that you'll have to create a new ZipArchive, copy all the entries across and then replace the original file with the new one. That's presumably what would have to be done behind the scenes anyway.
Actually, I tell a lie. You get a ZipArchiveEntry from the ZipArchive and then call its Delete method. I appreciate that you had a go at MSDN for yourself but that took me just a few minutes to find when I've never used these types before simply by reading all the relevant documentation. Don't just stick to one type. Follow the links. I went to ZipArchive, then ZipArchive.GetEntry, then ZipArchiveEntry just by clicking the links and reading, and there was the answer.
