Maybe this way:
select t.*
from table_name t
left outer join table_name t_del
on t_del.operation = 'Deleted'
and t_del.Filename = t.RenameTo
where t.operation = 'Renamed'
and t_del.ID is null
union all
select t.*
from table_name t
left outer join table_name t_ren
on t_ren.operation = 'Renamed'
and t_ren.RenameTo = t.Filename
where t.operation = 'Deleted'
and t_ren.ID is null
