Yes. If you test "the result" immediately after 'do'ing some applescript, it
will contain the result the of the applescript - or an error.
So for example
do "get 2 + 3" as applescript; put the result
is a very slow way to add; while,
do "get 2 + " as applescript; put the result
will put "compiler error".

There might well be a (better) way of doing this natively - and I suspect that
failing that you could do it better using the shell command - but to answer
your question, I happen to have just been looking at a really ancient stack
dating back to Mac OS 9, which included these functions:
put "set res to" && quote & quote & return \
& "repeat with p in the processes" & return \
& " set res to res & (the name of p) & return" & return \
& "end repeat" & return \
& "return res" & return \
get doAs(scrpt, "Finder")
replace numtochar(13) with return in it
delete first char of it -- quote
delete last char of it -- quote
function doAs cod, proc
put "tell application" && quote & proc & quote & return into asCom
put cod after asCom
if last char of cod <> return then put return after asCom
put "end tell" & return after asCom
do asCom as applescript
return the result
