I'm going to assume you're talking about Heat autoscaling here, in which
case the answer depends on which LoadBalancer resource you want to use.

The cloudformation-compatible LoadBalancer resource spins up a VM running
haproxy, with no dependency on neutron, but if you want to use the Neutron
LBaaS interfaces, and the OS::Neutron::LoadBalancer resource, you will need
Neutron ;)

Examples:
https://github.com/openstack/heat-templates/blob/master/cfn/F17/AutoScalingMultiAZSample.yaml

https://github.com/openstack/heat-templates/blob/master/hot/autoscaling.yaml#L151

In summary, if you want to make use of the native as opposed to
cfn-compatible autoscaling functionality, it's probably best to use
Neutron.
