The short answer seems to be "yes", with some potential gotchas. Namely,
"An ER-16 collet can sometimes be used in an E/EX-16 holder - but never the reverse i.e. an E/ES-16 collet in a ER-16 holder - if this is tried the extractor in the nut will ruin the smaller collet. Although the ER-16 collets will seat in the E/ES holder they will protrude more and the nut may not have enough threads to engage the body safely."

Mike
