Can I fit curtain track to this part of window?

[JONXLR8]

I have a Speedy Streamline curtain rail that I'd like to fit to a window.

Fixing details on curtain rail system here:

They normally just attach with wood screws so what I'd like to know is if I can safely screw them into the UPVC trim above the window in the following photo:

The trim is sturdy but obviously a hollow box section, will it be suitably strong enough to support a curtain?

What type of screws would be best for this?

For info there will be four of these fixings holding the rail and it's approximately 115cm long.

Thanks

Should be ok with self tappers assuming the boxing is securely fixed.
