Is it safe to upgraded to OpenLDAP 2.4 without testing compatibility/stability of it with our product?

In general it is never safe to upgrade without testing. Upgrading from 2.1 to 2.4 I wouldn't expect too many interop problems with your LDAP client app though provided you know what you're doing.

But when using multi-master replication you should be aware of some issues with data consistency when doing load-balancing/automatic fail-over between the replicas during several write requests.

Whether there is any issue with multi-master replication highly depends on the nature of your data and the behaviour of your application.
