Yes, you can use the SDK to remove relationships. Use the EnterpriseManagementRelationshipObject class. You can use the EnterpriseManagementGroup.EntityObjects.GetRelationshipObject* methods to retrieve collections of relationships or individual relationships.
Then you can use an IncrementalDiscoveryData object to remove the relationship objects.
Another method is to use an EnterpriseManagementObjectProjection to remove relationships between objects.
Here's a blog post with the basics:

Removing/Adding activities programatically is not as straight-forward as it might seem. Each activity has a "SequenceId" property. Activities MUST remain in sequence or the workflows will give you unexpected results. For instance, if you delete
an activity, for each activity that follows you must decrement its sequence id property. Similarly, if you add an activity, you must make sure that it's sequence ID falls in the proper order with the other activities (incrementing other activities as needed).
As a side note, BOVI Remy, the SDK is the primary entry point to the framework of Service Manager. The powershell cmdlets lay on top of the SDK. In other words, the cmdlets were created with the SDK. The cmdlets provide an abstraction layer to
make many SDK calls simpler. Basically, anything you can do with Powershell cmdlets, you can do with the SDK. Plus, there's even more that the SDK can do that you can't do with the Powershell cmdlets (currently). :)
