Some of it will have been disturbed/removed in 1986/1987 when they rebuilt her engine rooms etc. but the vast majority will still be there.
Asbestos is only a problem if it is disturbed, and turns to dust etc, as long as they left it alone, it didn't matter.
The recent refit of the "Rotterdam" for her static role as a hotel raised the same issues - I believe they removed all her asbestos while also then managing to replace most of her original interiors, presumably with modern fireproofing material.
