I've seen several vendors offering newer versions of zookeeper with Accumulo without issue. Cloudera has tested versions not too far off from Accumulo 1.4.5 and Accumulo 1.6.0 with CDH4, which uses ZK 3.4.5. Similarly, I just checked Hortonworks' documents on HDP 2.1 and that includes both Accumulo 1.5.1 and ZK 3.4.5.
I think the general answer is that yes, it will work. From what I've seen the ZK team does a good job of semantic versions, and minor releases should be backwards compatible. I've not seen any testing on ZK 3.5, but that will likely be fine too.
