BOAC;
Absolutely. The slush charts indicate a slight reduction in landing distance.
The "poor-to-nil" {ICE} case would perhaps be, at least at this stage and given previous landings, also academic and as EFHF has pointed out, would yield distances of over 3500m - difficult to square with previous performances in similar circumstances.
I believe from the chart the runway paved surface is 6365ft (just converting 1940m), with a 100m "overrun" area. The "Landing with no autobrake" chart is distance from 50ft to stop; The Airbus AOM does not state what the distance is in the ALD chart - whether it is from touchdown, or from 50ft.
