You should be able to get the prefix (D:\Dropbox\Portable) by using:

let $PORTABLE = fnamemodify($VIMRUNTIME, ':h:h:h:h')

You might need to change the number of :h's. There may also be fewer
:h's if you use $VIM instead of $VIMRUNTIME.

Then your command can become:

:%!$PORTABLE\ConvertZ\ConvertZ.exe /i:utf8 /o:big5

You may also wish to add ':8' to the modifiers, so that you get a
filename that will never have spaces in it.

See:
:help fnamemodify()
:help filename-modifiers
