Yes, it's fine. It has an internal charge controller and will not "over-charge".
It was some early rechargeable gear that used nickel-cadmium batteries and badly designed chargers that started the "things must be flat before charging" idea.
The charger ran for a fixed time, enough for a full charge, no matter what state the battery was... If it was not empty, it got cooked & wrecked...
All properly made modern gear uses "intelligent" charge controllers and you can start charging at any existing state of charge.
