No. The zsh man path says:

  A    As  `a',  but also resolve use of symbolic links where possible.
       Note that resolution of `..' occurs before  resolution  of  symâ
       bolic  links.   This  call is equivalent to a unless your system
       has the realpath system call (modern systems do).

but Linux doesn't have a realpath system call.

ypig:~> man 2 realpath
No manual entry for realpath in section 2


ypig:~> realpath symlink/../vlefevre/symlink

ypig:~> echo symlink/../vlefevre/symlink(:A)

where symlink is a symbolic link to ".".
