Brenda,
I wouldn't say no but rather I don't know yet (not sure of the syntax it might be supported).
For Access I have no idea about the SQL it supports. If it's as SQL server then would be possible. Off the top of my head :

update codes set code_name = ;
(select code_new from codes c, codes_conv cc where c.code_name == cc.code_old) ;
where code in ;
(select code_old from codes_conv)

PS: Just after posting I've great feeling it doesn't look right.

Update < bg > SQL server - Access might support this :

update codes set code_name = 
(select code_new from codes_conv 
   where codes.code_name = codes_conv.code_old)
