Is there a way to do in-place update the OS of an Azure VM, from within the Azure Portal?
i.e. from Windows Server 2012 R2 to Windows Server 2016

Nope. As per official article:

Microsoft does not support an upgrade of the operating system of a Microsoft Azure virtual machine. Instead, you should create a new Azure virtual machine that is running the supported version of the operating system that is required and then migrate the workload.

https://support.microsoft.com/en-us/help/2721672/microsoft-server-software-support-for-microsoft-azure-virtual-machines

Instead, use the Windows Server Migration Tools to assist you in roles and features migration:

Install, use, and remove Windows Server migration tools

    This article talks about automatic upgrade of Azure VM .The automatic OS image upgrade feature for Azure scale sets will automatically upgrade all VMs in your scale set to the latest version.https://www.pressreader.com/@Max_Brodin/6786250207940378 – roney Aug 13 '19 at 18:06

No, there is no such ability to upgrade an OS on the Azure VM (and not that I heard about it in future, who knows thou).

It can be done by downloading the VHD and doing the upgrade locally with Hyper-V and then reupload it.
