Sure:

define service {
host_name hostA,hostB
service_description chef-server
use default-service
check_command check_chef-server
}

Similar happens with multiple host groups:

define service {
use default-service
service_description disk
hostgroup_name aix,base,solaris-base
check_command check_disk
}
