It is not possible to create a variable with a name similar to 1Tn007
What can happen is that if you load() a .mat that was generated by a third-party tool, and the .mat had a variable that is a struct, then the struct can end up with invalid field names. If the invalid names were the names of variables, then MATLAB will refuse to load that variable.
If you are are trying to load a .mat with invalid names, then see https://www.mathworks.com/matlabcentral/fileexchange/42274-loadfixnames-loads-a-mat-file-fixing-invalid-names
