The name a variable or object / class is something that appears in the ide environment but is lost in compilation, so in execution asking for a name makes no sense.
This is especially true for those variables that are indicated by reference.

You can achieve a similar thing with the Map though.

B4X:

NameList.Put(List,"Name")
NameList.Get(List)

Yes

B4X:

Dim NameList As Map
NameList.Initialize
Dim MyList As List   
MyList.Initialize   
NameList.Put(MyList, "MyList")
Log(NameList.Get(MyList))

or

B4X:

    Dim Name As String = "MyList"

    Dim MyList As List
    MyList.Initialize
    
    Dim NameList As Map = CreateMap(Name : MyList)
    NameList.Get(Name).As(List).AddAll(Array As Int(1, 2, 3, 4, 5))
    Log(NameList.Get(Name))
