Yes you can
You will definitely want to check if the ASM diskgroup spans volumes. If it does you must enable the NTAP_CONSISTENCY_GROUP option and I would set the NTAP_CONSITENCY_GROUP_TIMEOUT to medium (this is default). I would also use the oracle plugin to ensure database is in backup mode when snapshot is taken. If you just care about point in time backup and recovery then you can get away with just snapshot which would be crash consistent.
