Certainly. Even better, you could write
d e f g b c d e f instead of d' e' f' g' b' c' d'' e'' f''
since for every interval, it will use closest option.
So, if for example the previous note was a "c" and you 
ask for a "g", you'll get the g one fourth below the
c rather than that one a fifth above. 

If you mostly stay within an octave but have several 
steps larger than a fourth, you may prefer to use
\transpose instead. Example:

\transpose c'' {c b d a c g d b c}
