Microsoft documents the following information:
In SQL Server 2016, you can create a new database by restoring a backup of a user database created by using SQL Server 2005 or a later version. However, backups of master, model and msdb that were created by using an earlier version of SQL Server cannot be restored by SQL Server 2016. Also, SQL Server 2016 backups cannot be restored by any earlier version of SQL Server.
It means that it is possible to restore a backup from SQL Server 2005 and later in SQL Server 2016.
