If we were really trying to deduce the age of Urth from the text, it 
must be older than that.  At several points Severian mentions the lack 
of volcanic activity on Urth and the solidification of the Urth's 
interior.  I'm not a geologist, but a few million years, or even a few 
tens of millions of years, isn't going to cut it if we assume that 
volcanic activity has ceased due to natural cooling and decay.

But since Wolfe is not a hard SF writer I wouldn't make too much of it.
