Well, provided you don't uninstall the APK, yes.
The install may ask for around 2-4GB of free space to install properly.
Because Android.
Still, it's a good practice to make backups of your savegames.
So get a file explorer like MiXplorer, SolidExplorer or X-Plore
And go to Android/data/com.domain.corruptedkingdoms/files/saves
There you grab the contents of the saves folder and copy them somewhere else.
If you uninstall the game and install it back again you will have to do the same process but backwards to put them back into place.
