No, you cannot use an alias in Cognos Insight as you can in TM1:
In Cognos Insight you cannot use an alias instead of the corresponding element name as you can do in TM1.
In Cognos Insight, when importing data say from a flat file, you can define an alias in the data source and map it to an element.
In short terms, in Cognos Insight a TM1 alias is restricted to the role of a lookup element in a lookup dimension when importing data, quote the IBM Cognos Proven Practice "IBM Cognos Insight - Map Members from Different Sources to the Same Dimension":
"This scenario can be dealt with in Cognos Insight by using Aliases or a lookup dimension."

IBM Cognos Insight - Map Members from Different Sources to the Same Dimension
Summary: Experienced data modelers can use the techniques in this article to map members from different data sources to the same dimension during an import into Cognos Insight 10.1 or 10.2. They may be used when measures are taken from two data sources and the members from the dimensions bringing context to the measures do not match.
