Yes Microsoft Teams for Linux too: Microsoft released the Teams app a group chat program for the Linux platform as a preview yesterday, December 10th.
No it is not April Fool's Day, Microsoft Teams for Linux is already available for λήψη from today in .deb and .rpm formats (Link at the end of the post). Company officials said that all the basic features of the application will be available for Linux users as well.
A Microsoft blog post states that "Microsoft Teams is the first Office application to run on Linux desktops."
Is Microsoft hinting that we might see that too OneDrive or some other Office apps on Linux?
No one knows, as there is still no official placement. It would be interesting, though, as Microsoft's popular Office would have to compete for free LibreOffice.
Microsoft already offers the Teams app on Windows PCs, Macs, iOS mobile devices, and Android but also on the Web through the browser you use. It is the competitor of the Sack application that already has a client for Linux.
