@Shaunak, No, it's not safe to uninstall any application if it's dependency packages
are being used by some other application. There are some applications like Games,
you can uninstall them if you want to. There is no harm in doing that.
If you remove(ie., delete) whatever you don't need then your Ubuntu Linux
will be screwed up totally!!! That's not the proper way to uninstall a application.
Remember if you remove certain packages & it's dependency packages , it may be
used by some other application!! If you start some application, it will tell to install
the dependency Packages first!!! So better double-check before you remove any
application.
