Yes, it is safe to install. The libKF5* packages are perfectly coinstallable with the KDE4 packages.

But libKF5something is only needed by the KF5 breeze style. That one is for KF5/Plasma5 and won’t work at all with KDE4.
You need breeze4-style to use the breeze style in KDE4-based applications. And this one should not pull in any libKF5 packages either.

OTOH, YaST e.g. would need breeze5-style as it is Qt5 based.
