But it is strange don't get the same warning between Ubuntu 14.04 and

I assume the licensecheck regexes changed. Michael may need to be running 16.04 to test this with any accuracy.
By way of explanation:

licensecheck is a tool that checklicenses.py uses - but is *not* something we ship, which means that

	1) if you don't have it installed on your system, checklicenses.py won't work, and I suspect only (some?) Linux distributions provide it as part of the distribution (and even there you might have to install the right package - in particular, Microsoft don't, as far as I know, ship it with Windows;

	2) if version X.Y of a given OS has one version of licensecheck, and version X+1.Z of that OS has a different version, and the two different versions behave differently, that could cause checklicenses.py to behave differently on the two different versions of that OS.

So

	1) checklicenses.py might not work on Windows unless you install licensecheck

and

	2) checklicenses.py might start coughing up a lot more errors if upgrading from Ubuntu 15.whatever to 16.whatever gives you a new version of licensecheck that behaves differently in a way that causes more license complaints.

(I just discovered this a few minutes ago, when I went looking for licensecheck.  It doesn't ship with OS X, either.)
Right, it's a debian provided package maintainer helper script.

Debian derivatives will have it, other distros probably not.

Non-Linux systems almost certainly won't provide it.
