Yes based on this http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-...

Assign Node Labels to Cluster Nodes

Use the following command format to add or replace node label assignments on cluster nodes:

yarn rmadmin -replaceLabelsOnNode "<node1>:<port>=<label1> <node2>:<port>=<label2>"

For example, the following commands assign node label "x" to "node-1.example.com", and node label "y" to "node-2.example.com".

sudo su yarn
yarn rmadmin -replaceLabelsOnNode "node-1.example.com=x node-2.example.com=y"

yes you can assign multiple nodes to a label, that's the premise of node labels, you want to designate GPU heavy nodes to node label GPU, nodes with SSD to label SSD, etc, the label needs to be shared and not exclusive. Here's design PDF and yet another PDF for node lables and associated Jira.

Here's a screenshot from the first PDF:
