BTA16 absolute maximum amperage at 220/240V 50hz and impact of snubbers on resistive loads?
Yes, it can handle 16A. Triacs are forgiving parts. Peak current can be ten times higher without destroying it.

The snubber may have the side effect of mains driven LEDs or neon lamps on the part light up though the thing is "off".

By the way: BTA16-600CW is a snubberless part. You simply don't need the snubber.
