Yes it is possible to uninstall a package in Android. Moreover you can also skip asking user to press OK button on uninstall screen. You can do it by using Accessibility service in Android.

public class MyAccessibilityService extends AccessibilityService {
    private static final String TAG = MyAccessibilityService.class
            .getSimpleName();

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {
        Log.i(TAG, "ACC::onAccessibilityEvent: " + event.getEventType());

        //TYPE_WINDOW_STATE_CHANGED == 32
        if (AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED == event
                .getEventType()) {
            AccessibilityNodeInfo nodeInfo = event.getSource();
            Log.i(TAG, "ACC::onAccessibilityEvent: nodeInfo=" + nodeInfo);
            if (nodeInfo == null) {
                return;
            }

            List list = nodeInfo
                    .findAccessibilityNodeInfosByViewId("com.android.settings:id/left_button");
            for (AccessibilityNodeInfo node : list) {
                Log.i(TAG, "ACC::onAccessibilityEvent: left_button " + node);
                node.performAction(AccessibilityNodeInfo.ACTION_CLICK);
            }

            list = nodeInfo
                    .findAccessibilityNodeInfosByViewId("android:id/button1");
            for (AccessibilityNodeInfo node : list) {
                Log.i(TAG, "ACC::onAccessibilityEvent: button1 " + node);
                node.performAction(AccessibilityNodeInfo.ACTION_CLICK);
            }
        }

    }

    @Override
    public void onServiceConnected() {
        Log.i(TAG, "ACC::onServiceConnected: ");
    }

    @Override
    public void onInterrupt() {
        // TODO Auto-generated method stub

    }
}
