Not really. Both Intel and AMD do weird non-RISCy things beyond the decode stage.
The original difference between RISC and CISC was that RISC eschewed arithmetic+memory-operations in the same instruction. Both Intel and AMD processors violate this commandment. Instead their decomposition of instructions into uops is based more on the more pragmatic notion of choosing uops that are easy to pipeline and execute out of order.
