No.

Specifically clause 2(i):
"No right is granted to [...] use the ARM Architecture Reference Manual for 
the purposes of developing or having developed microprocessor cores or models 
thereof which are compatible in whole or part with either or both the 
instructions or programmer's models described in this ARM Architecture 
Reference Manual"

You may argue whether qemu constitutes a "microprocessor model". However the 
ARM licencing/legal department have stated that in their opinion it does, and 
is covered by this clause.

Also note clause 2(iii) that prohibits redistribution of the document.
