In case you were wondering whether AX 2012 RTM will run on SQL Server 2016, have a look at this video:

The AX kernel version used is 6.0.1108.8690. SQL Server 2016 was installed with all default options. The database was restored from a SQL Server 2008r2 AX database. This database has compatibility level 100.
While this seems to work fine, at the moment this is probably not a supported configuration.
